Originally, operational amplifiers (op amps) were not thought of as candidates for RF design, but the advent of newer, faster devices has now made them an attractive option for some applications. The ...

What every RF design engineer needs these days is a good all-purpose IC RF amplifier. You don’t want to have to design basic circuits like this yourself. Yet the need is always there for a gain block ...

Important efficiency requirements exist on both the handset and the base-station sides of the telecom world. In handsets, efficiency directly translates into battery life. By increasing cell-phone ...

In the 1980s radio frequency (RF) engineers developed microwave and millimeter-wave integrated circuits that revolutionized the reliability and controllability of RF systems, while significantly ...

With 14 envelope-tracking-enabled handsets now on the market, and more sets to follow in the coming years, envelope tracking (ET) has been firmly accepted as the industry standard for the architecture ...

The number of RF filters in a typical smartphone is expected to reach more than 100 in 5G devices, writes Bob Hammond – EDA tools for RF filters are available, but they are under‑used. The RF filter ...

The next-generation 4G wireless standard known as long-term evolution (LTE) presents some new and difficult design choices for OEMs. One of the more difficult choices involves the less glamorous, but ...
